Overview

Release notes

What's included?

Free trials

Smaller, faster, smarter code

Make sure your code is the best it can be. Our compiler makes it fast, effective and highly compact. And powerful code analysis ensures its quality. The compiler and the debugger of IAR Embedded Workbench are by many considered the best in the industry.

Working with safety-critical applications?

The functional safety versions of IAR Embedded Workbench are certified according to IEC 61508, the international umbrella standard for functional safety, as well as the automotive standard ISO 26262.

Latest benchmarks

We are proud of the benchmarks we get.

Outstanding speed optimizations enable IAR Embedded Workbench to generate very fast performing code. With the shortest possible execution times it is the ultimate choice for developing low-power applications.

EEMBC is a non-profit industry association for embedded microprocessor benchmarks. EEMBC CoreMark is a simple, yet sophisticated, benchmark that is designed specifically to test the functionality of a processor core. Running CoreMark produces a single-number score allowing users to make quick comparisons between processors.

Support for new devices

IAR Embedded Workbench for MSP430, V6.50
Released June 23

Extended functionality in C-STAT

The static analysis tool C-STAT has been extended with approximately 150 new checks including 90 new MISRA C:2012 checks and two new packages of checks. There are also new options to enable or disable the false-positives elimination phase of the analysis and to exclude files from the analysis. C-STAT message suppression can now be controlled by directives placed in comments in the source files.

Extended inline assembler

The inline assembler has been extended with the possibility to take input arguments, have return values, and read or write to C symbols. The syntax is similar to the syntax used in GNU GCC.

Support for new devices

Support has been added for the following new MSP430 devices: MSP430FR2110, MSP430FR2111

Sampled Graphs in C-SPY

Saving C-SPY Watch window content

In the C-SPY Watch window family, you can now choose Save All to File from the context menu to save the contents of the current window to a text file.

New windows for C-SPY macros

Three new C-SPY windows have been added to easier manage C-SPY macros. The Macro Registration window controls which macro files are loaded and the Debugger Macros window shows a list of all macros available in the debugger. The Macro Quicklaunch window makes it possible to evaluate expressions and to launch C-SPY macros.

External analyzers

A flexible mechanism to invoke external analyzers for project files. This is typically used as an interface to static analysis tools like PC-lint.

Custom argument variables

Custom argument variables can be used in the IAR Embedded Workbench IDE whenever there is a need for a macro-like expansion that depends on the current context. This could for example be in arguments to an external build tool.

Call Graph window

A new Call Graph window has been added. It is browsable and displays all calls made to and from each function from any source file in the active project.
